The Electrical Safety Roundtable (ESR) has launched new guidance to help consumers make informed and safe choices when buying, installing and using plug-in solar devices.

The ESR is reminding consumers that there is more to consider than simply buying a device from a supermarket, DIY store or online retailer. The aim of the guidance is to encourage safety by explaining the checks and precautions needed to help ensure these systems are compliant, suitable and installed correctly.

A compliant plug-in solar device should meet the Plug-in Solar Device Interim Product Specification and be clearly marked and accompanied by a statement confirming compliance.

The product labelling should identify the manufacturer, model or serial number, voltage, frequency, current, rated power, IP rating and protection class. Consumers should buy from reputable suppliers, follow all instructions and never modify the plug, cables, inverter, panels, connectors or other supplied components.

Ideally, the device should be connected to a nearby suitably located and protected external socket-outlet. Cables must not be trapped in doors or windows, as this may damage them. Poorly routed and secured cabling can create trip hazards and further risk of damage.

Before purchasing a plug-in solar device, the ESR strongly recommend that consumers find a qualified and competent electrician to perform the necessary checks on their electrical system before installing plug-in solar.

Also, consumers should contact their insurer before purchasing a device. People living in flats or apartments may also need approval from the building owner, while tenants must seek permission from their landlord. Managing agents, planning authorities and other interested parties should be informed where applicable.

After installation, the Distribution Network Operator must be notified within 28 days. The instructions supplied with a compliant system should explain this process.

The guidance provides a resource for anyone supporting consumers considering plug-in solar. Letting agents and landlords can share it with tenants and residents to explain the permissions and safety checks that may be required.

Organisations can use it to raise awareness and signpost consumers to clear, consistent information. Electricians can also share it with potential customers to help them understand why checks by a qualified and competent electrician are important before installation.

By making the guidance widely available, ESR aims to help consumers benefit from plug-in solar while ensuring safety remains the priority.

Nick Hayler, Chair of the Electrical Safety in the Home group said: “We support innovation that can help households embrace renewable energy and reduce their bills, but it has to be done safely. Consumers should follow the guidance and use a competent and qualified person to help ensure their plug-in solar device is suitable and installed correctly.”
